Our friend had told us about this farmer's market when we visited Maui back in 2010. We enjoyed it then and had stopped by again on this trip December 2012.
It seemed though that this time around the market was even smaller with less vendors--under 10. Most vendors sell fresh seasonal produce like island fruits and some veggies. Not much going on, but it's a relaxed little place in a great little town center. You could walk up and down the street to checkout the other stores or grab a bite at one of the cafes.
The market is set up in a small lot on Wednesdays and Saturdays.
